A further object of my invention is an improved means for gaining access to the filling appliances ina vending machine.

A further object of for collecting the coin and to the coin collecting means.

improved means obtaining access A further object proved slug detecto A further object. of my my invention is an of my invention is an imr and ehmmator.

lnvention 1s the providing in connection with the visibility as to contents means for protection from surreptitiously rem oving the contents.

\Vith the foregoing and other objects in View, my invention consists of the novel construction, combination and arrangement of parts as hereinafter specifically described and illustrated in the accompanying drawing, wherein is shown the preferred embodiment of my invent ion,-but it is understood that changes, variations and modifications can be resorted to .which come within the scope of the 'claimhereunto appended.

While my invention relates primarily to a food vending machine,

for containing pies and sandwiches and other perishables of that character, I do not wish to be limited to those articles.

I am aware that there area great many vending machines similar in appearance to the one herein-described, many much more complicated and but few, if any,

more expensive to construct, that have so few parts and none of such simplicity ofconstruction with the p protection after 16d my design.

especially adapted In the drawings of the herein-described embodiment of my-invention, Fig. 1 is aperspective in use. Fig. 2 is a face view the interior parts of the machine broken off and removed from the case. Figs. 3 and 4. are the two side views in elevation respectively of the interior of the machine removed from the case broken off, asshown in Fig. 2; Fig. 5 is a sectional-view taken through 5-5 of Fig. 4'; Fig. 6 is an enlarged sectionalview in elevation of the bottom of the casing and lower front; Fig. 7 is an enlarged perspective view of the undersize coin-detector; Fig. 8 is a plan View of the undersize coin-detector shown in Fig. 7 Fig.9 is a sectional view of the undersize coin-detector taken through 9-9 of Fig. 7

Fig. 10 is a view taken through 10-10 of Fig. 7, and shows the third; coin-detecting means; Fig. 11 is an enlarged view of the coin shield taken in elevation; Fig. 12 is an end view in elevation of the coin shield shown in Fig. 11, and'Figf13 is a. plan view of the coin shield shown in Fig. 11.

Similar numerals refer to similar parts throughout the several views.

1 is the main outside casing; it is provided with upper front 2 and lower, front 8. t is the top cover which'is hinged on the back of the casing 1 and is provided with means for folding down on the topof casing 1, being locked to upper front 2 when in position by lock 6, thelower end of upper front locked in front of lower. front 3 by lock 7 at its upper end, the lower part of lower front 3 being caught under outside casing 1 in a hinged fold at 5.

The arrangement of the upper and lower fronts are such that the operator in filling the machine need not unlock lock 7, thus maintaining the mechanism and coin box out of his. reach.

Within casing 1 is placed the operating part of the vending machine which consists of'magazine 8 and table 9 provided with supporting flanges 10 upon which rests the goods 11, to be sold. Under supporting'flanges 10 operates slide 12 provided with hook projections 13, the object of the-hook being to form a finish on the top of the projection of such a character as to permit of its retrieving movement under the weight of the goods above the same, without injury to the package.

View of the machine assembled as 1n elevation of,

2 being coin shield drops from coin. shield 30 Slide 12 is provided with draw-bar 14;, at the end of which-is a ring 15, or other suitable or convenient means to grasp with the fingers. This draw-bar 14: operates through lower front 3, the front being slotted as shown to permit ring l to go through the same, said draw-bar being I front end of the table by guide 16. Slide 12 is provided with retrieving means, shown as a spring 17, in the drawings.

18 is a hook, or coin-operated locking means, for slide 12, and is fulcrumed to the coin shield at 19 and engages over projection. 20 under the slide 12, thus preventing the slide from operating when in. retrieved'position'. To raise hook 18 in order to release projection 20 a coin, 21, of the correct dimension is necessary. A coin is introduced through the upper front 2 at coin slot 22, which slot is substantially the size of the proper coin, thus acting as a first check on the coin for over-size. The coin in its pregress goes down chute 23, in which chute'on the upper edge is an undersized coin eliminator consisting of a means 2 1 for tilting the coinout of the vertical to a limited extent, causing the same to bear against top chute guide 25, if of proper size; if under-size, however, it will miss top chute guide and fall over into the outsi le casing and not follow the chute to the releasing mechanism, thus forming the second protective device.

The coin of the proper size in its progress comes to elbow in the chute, at which point is magnet 27, the chute at about this point being cut away to permit a slug of magnetic metal to be attracted from its line of progress in the chute to opening 28 where it is eliminated from the chute and dropped into the outer casing, this forming the third protective device.

The coin, dropping through the lower or vertical section of 29 of the chute, enters the 30. Hook 18 is fulcruined to this shield, said shield being secured to the table 9. The coin engages hook 18 at or near its fulcrum.

In coin shield 30 operates coin push projection 38, which projection is secured to slide 12 operating through. slot in the table and behind the coin, so that upon pulling slide 12 bymeans of ring 15, push projection 38 carries the coin with the slide and in doing the coin lifts the hook around its fulcrum tosuch an extent that it disengages hook projection 20 under the slide, there being sufficient back-lash to permit of this movement. The slide being free may be pulled to the limit of its action, and in doing so it pulls the bottom package of goods 11 with it by means of book projection 13; The coin, near the limitof' the slide withdrawal, into the coin receptacle 3-1.

Coin receptacle 31 consists of a funnel steadied at the,

in bands, then drawing box hinged at its lower end at 32 so that it may be easily tilted to discharge its contents and be replaced in position again and is formed out of a single piece, as shown.

Specially referring to the coin shield, 30,

hook 18 fulcruined thereto and being pro vided with coin guide a, lower runway of the chute Z2, definitely spaced with reference to the fulcrum end of the hook so that it requires an exact size coin to lift the hook sufficient to disengage the slide; it is also provided with spacing and aligning members 0. In fact, by one operation it is formed ready for assembly. 1 j

The slide being pulled out with the lowerpackage of goods, upon reaching the ends of supporting flanges 10 the goods fall off into delivery chute 33, where they can be reached by the purchaser.

Hook projections 13 are fulcrumed to the slide so that they are normally held in po sition, as shown in Fig. 2; that'is, in en'- gaging position, a spring or: other dcsir' able means 7 operation they operate when inthis position until the delivery of the lower package of goods; when the package over the same drops on top of these projections they yield to the same and slide under the lower package during the. retrieving move ment of the slide until th y are behind the lower package and free to regain their nor-v mal position.

41 is a slot closer to automatically prevent the introduction of a coin when the machine is empty, and is fulcrume'd at 35, forming a bell-crank the other end of which is secured by means of a link 36 to hell-- crank 37, the other end of bell-crank 3? be ing a pedal,- or projection, under the goods in the magazine and held down by thesa'me; when 1' say bell-crank 37', I mean a shaft provided with a pedal on one end and at the other end a crank so that the-j-pedal' may be in the rear of the machine when the lever is at the front of the niacl'iin'e, thus forming in substance a-bell-crank operation; the shutter operates directly behind coin-slot inupper front in front of chute 23, the weight of 'link- 36 being suf licieut to close the slot closer when there are no goods on the pedals.

The operation of my invention is as follows: s

Themaehine being assembled as shown in Fig. 1, the magazines are-filled by opening top cover 4 and int'roducing'the' package's out the hands This, however, is not necessary,- but is simple way of filling. The? coin removed by flak ing off both fronts and tipping the" money being used for this purpose. In 7 box, as previously suggested. The slugs are scraped out of the bottom of the casing and are not found in the money box. v

Having thus described my invention, What 5 I claim and desire to secureby Letters Patent is:

In an organized Vending machine provided With a coin controlling apparatus, a

coin shield consisting of stamped sheet metal 10 provided with a lower runway, a guide at said fulcrum being such that a proper sized coin ienteringsaid guide operates said hook to lift the same when pushed along said runway by said slide.
